Hi list,
just to share my solution. Now I've both TTLS+PAP+LDAP and
PEAP+MSCHAP+LDAP work.
My LDAP server lives on CommunigatePro, and store password in various
mode. This is not a problem for bind operation (TTLS+PAP), but have
to be configured specifically for ldap search, method used by
PEAP+MSCHAP.
So problem didn't live in Freeradius.
Regards,
Paolo.
